arracnmmir FOR SCALES.

Specification of Letters Patent.

Application filed October 19, 1916. Serial No. 126,468.

To all whom it may concern. I

Be it known that I, CHARLnsE. RIEDEL,

a citizen of the United States, residin at mobile tires, may be cited.

' Other objects of this invention reside in the provision ofimproved indicating and weight compensating devices adapted for attachment with the aforesaid supplementary devices. These. devices are generally .known as "scoop weights and they are commonly used to counterbalance a scale for the weight of a scoop and to indicate to the customer and clerk that such compensation has been made. The improvements in the scoop weight will be pointed out in more detail 111 the accompanying s ecification.

Other objects resi e in themodification of a scale of the type shown in the patent to Hopkinson and Ozias #867,671, whereby sacks of grain and similar high articles may be weighed without interference with the main scale beam.

Other objects of this invention will be pointed out in detail in the accompanying specification.

In thedrawings:

Figure 1 shows a front elevation of a scale of the Hopkinson & Ozias type and shows the scoop weight in on posltion and one of in improved attachments in place on the plat orm to adapt the scale for weighing a coil of material such as wire or rope.

Fig. 2 is a top plan view of the scale weight device the latter figure showing the weight 1n cooperation with the scale beam.

Patented Feb. 8, 1921 Fig. 8 shows another modification of the device used for weighing coils of material on a platform scale.

7 Fig. 9 is a rear view of a portion of the scale, showing the scale beam indication with the scoop weight in off position.

I In more detail Fig. 1 shows a scale havmg a base 10, chart housing 11, weighing and computing chart 12, indicating hand 13. The platform 14 is supported upon the usual supporting levers in the base and these connect with any desired counterbalancing attachment, for example, those "shown in Patent No. 867,671. The platform is preferably provided with overhanging lips 15 which prevent any material spilled thereon from getting inside the base 10. The main scale beam 16is fulcrumed u on a pedestal which is supported-upon t e chart housin height as'shown in Fig. 1 to permit high artlcle's such as sacks of grain to be Weighed upon the platform without interferencewith the graduated beam 18. The graduated and this pedestal is of considerable beam is secured to brackets fastened to the scale .beam 16 and carries the usual sliding polse. The high pedestal construction provides a ready access to the poise when high articles are being weighed upon the usual trig loop and limits'the extreme movement of the beam.

With platform scales of this ty e it is frequentlydesirable to weigh coile material and other articles which would roject beyond the platform if placed 1; ereon. Such articles have heretofore been weighed on various forms of hanging scales. To

I M platform. A second hlgh pedestal 20 forms the weigh such articles I provide an attachment or supplementary device consisting of a bar 21. curved to correspond with the contour of the platform. This bar is of such length that its ends project beyond the sides of the platform, as shown in Figs. 1 and 2. The bar has securedthereto hook members 22 ,which are spaced to extend under the lips 15 of the platform. The hook members are secured to the bar by screws and are preferably hollow to provide recesses to receive lead. The lead is added to or removed from the recesses, asmay be necessary, to bring the bar and its attached hook members to a certain desired weight. It will be understood that it is necessary to compensate for the weight of this bar (in a manner which will be hereafter explained) and the lead pockets provide a ready means for bringing the bar to a certain definite weight which can be compensated for. The use of the bar is-self evident from the drawings. The bar is slipped in place on the platform and the projecting ends form a support for the material, such as for example, a coil of wire. The hook members 22 prevent a preponderance of weight on one arm from tipping the bar. At the same time the'b'a'r can be quickly removed from the scale without unfastening any parts and when not in use can be hung up adjacent the scale.

In Figs. 4 and 5 is shown a modification in 'which the platform 14 is grooved as shown at 24. Bars 25 are placed in these grooves and are pivoted at their outer ends to the scale platform. By swinging the bars pivotally outward to the dotted line position, they will form a platform extension or support which is adapted to receive a coil of wire or other material normally too large to rest properly on the platform.

Fig. 8 shows another modification in which a series of bars 26 are adapted to slide in and out of the platform to form an extension, in a manner which will be readily understood.

It will be understood that with the modifications shown in Figs. 4, 5 and 8, it will not be necessary to compensate for the weight of the bars 25 or 26 as they are always associated with the platform and their weight is constant whether extended or not.

Fig. 3 shows supplementary devices arranged to weigh a large coil such as an aushown in Figs. 1, 2 and 8'are used it is necessary to correct the scale for the weight of the attachment. I provide a pivoted scoop weight for this purpose. The device is generally termed a scoop weight since it is frequently used to compensate for the weight of a scoop on the platform and it is to be understood that the device now to be described is adapted for that use as well as for compensating the scale for the weight of the supplementary devices herein described.

With scales equipped with scoop weights, the sealers of Weights and measurements requirements are that these devices must not be removable and also that the customer must be plainly shown whether the scoop weight is on or off. With the construction here employed a bracket 30is securely fastened to the main scale upon the free end thereof and to the right of the trig 'loop 20. The bracket carries a boss which extends between the forked ends.of an arm 32 carrying the scoop weight. A pivot 0r pintle 31 extends through the boss and the forked ends of the arm 32 and this pintle is retained in place in the boss by means of a pin (not shown). The end of the arm 82 remote from the pivot 31 is recessed as shown at 33 in Fig. 6 to receive lead and by varying the amount of lead in these .pockets the weight of the scoop weight may be varied. It will be understood that the scoop weight is adapted to rest upon the scale beam horizontally to the left and the right of the pivot 31. When in the latter position the scoop is effective to counterbalance the scale for the weight of the scoop or other supplemental device and when to the left of the pivot the scale beam is in balance when the supplementary devices, are not in use. By reason of the pivoted construction the scoop weight must take one or the other position, and as it is pivoted to the free, end of the beam the compensating action is better than with constructions in which the scoop weight is pivoted to the left of the fulcrum of the beam. In order to take up the shock of impact of the scoop weight and beam I provide a blade spring 34 which is adapted to support the weightedend on the beam as shown in Fig. 7.

In order to indicate to the clerk and the customer the position of the scoop weight I provide an indicating plate 35 which is sesecured to the weighted end of the arm 32. This plate on the clerks side has two sets of characters. The characters Scoop on appear uppermost when the scoop weight is to the right in the compensating position. The characters Scoop oflt' appear uppermost when the scoop weight is resting on the beam to the left of its pivot. The rear of the plate has indicating characters reading Scoop on thereon which are adapted to show to the customer at the opposite side of the scale when the scoop weight is in com-- pensating position. The lower portion of the plate 35 is adapted to obscure characters on the scale beam reading Scoop off. \Vhen the scoop weight is swung to the opposite side of the pivot to off position, the plate moves from in front of these characters and displays them to the customer as having a scale beam adapted to permit the which would extend weighed, an
